Drive Hub Oil Seal Extractor for CAV DPA Pumps – Ref. 7044-893A

MARBED 9279 is a drive hub oil seal extractor designed for servicing CAV DPA rotary diesel injection pumps.

The tool is used during pump disassembly to extract the drive hub oil seal from the pump housing after removal of the drive shaft, governor weight assembly and drive hub.

Its long, slender design allows the extractor to reach the oil seal through the drive end of the pump and remove it from its seat without the need for improvised extraction tools.

The 7044-893A reference is identified in CAV DPA workshop documentation as the special tool for removing the drive hub oil seal. Historical MARBED documentation lists the 9279 oil seal puller under reference CAV 7244-334.
